Solution Overview
Problem
Existing optical transceiver modules require complex configurations and numerous components, leading to increased costs, equipment requirements, and man-hours for adjustment and testing due to the need for precise temperature control of laser diodes and avalanche photo diodes.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If optical transceiver modules are used to control temperature properties of laser diodes and avalanche photo diodes, then temperature control precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The invention extracts the temperature control function from the optical transceiver module and implements it separately on the host board. The optical module only contains the light emitting element, light receiving element, and memory circuit, while the control circuit resides on the host board, separating concerns and reducing module complexity
Solution Approach 2:
The memory circuit acts as an intermediary that stores property data of the optical elements and provides it to the control circuit on the host board. This mediator enables precise control without requiring complex internal circuitry within the optical module itself
2Reliability
If optical transceiver modules with control circuits are used, then temperature control capability is improved, but manufacturing cost increases
Solution Approach 1:
The control circuit is extracted from the optical module and placed on the host board, reducing the bill of materials for the optical module itself and allowing standard optical components to be used without expensive integrated control solutions
Solution Approach 2:
The system uses the existing property data of the optical elements (stored in memory) to enable self-control. The control circuit on the host board reads the property data and automatically adjusts driving conditions, eliminating the need for external temperature control equipment or manual calibration
3Reliability
If optical transceiver modules are used for temperature compensation, then operational reliability is improved, but man-hours for adjustment and testing increase
Solution Approach 1:
The property data of the optical elements is pre-measured and stored in the memory circuit during manufacturing. This preliminary action eliminates the need for time-consuming field adjustments and testing, as the control circuit can directly use this data for optimal operation
Solution Approach 2:
The control circuit on the host board continuously monitors the optical element performance and adjusts driving conditions based on the stored property data and actual measurements, providing automatic feedback control that maintains reliability without manual intervention

AI summary
The present invention provides an optical module, a host board, and a method of manufacturing the host board, where the number of man-hours required for manufacture has been reduced. Accordingly, the present invention need not have such type of optical transceiver module as the conventional host board since the host board on which the optical module has been mounted may automatically perform a control corresponding to property data of a light emitting element and a light receiving element by mounting a memory circuit on the optical module. As a result, it may be achieved to provide an optical module, a host board, and a method of manufacturing the host board, where the number of man-hours required for manufacture has been reduced.
